Datalabels are not displayed when many charts are added to the combined chart

[Hyjeon830]

I added StackedBarChart and LineChart in CombinedChart, but even if setDrawValues is true for all data, the DataLabel values are not displayed.
What is the solution?

I attach the source code below.

var barEntries = ArrayList()
var linePlanEntries = ArrayList()
var lineTotalEntries = ArrayList()
var lineRateEntries = ArrayList()
var xAxises = ArrayList()
var maxTotalPrice = 0f

    var i = 0f;
    dataMap!!.toSortedMap().forEach { (key, value) ->
        var strKey = key

        if(key.length >= 8) {
            strKey = key.substring(5)
        }
        else if(key.length >= 6) {
            strKey = key.substring(2)
        }

        xAxises.add(strKey)

        barEntries.add(BarEntry(i, floatArrayOf(value.second.dReadyAmount.toFloat() / 10000f, value.second.dCncAmount.toFloat() / 10000f,
            value.second.dCo2Amount.toFloat() / 10000f, value.second.dUvAmount.toFloat() / 10000f)))

        val totalPrice = value.second.dReadyAmount.toFloat() + value.second.dCncAmount.toFloat() + value.second.dCo2Amount.toFloat() + value.second.dUvAmount.toFloat()

        if(maxTotalPrice < totalPrice / 10000f)
        {
            maxTotalPrice = totalPrice / 10000f
        }

        linePlanEntries.add(Entry(i, value.first.toFloat() / 10000f))
        lineTotalEntries.add(Entry(i, totalPrice / 10000f))
        lineRateEntries.add(Entry(i, totalPrice / value.first.toFloat() * 100))

        i++
    }

    val combinedData = CombinedData()
    val barData = BarData()
    val lineData = LineData()

    val barDataSet = BarDataSet(barEntries, "")

    barDataSet.colors =  ColorTemplate.MATERIAL_COLORS.asList()
    barDataSet.valueTextSize = 5f
    barDataSet.stackLabels = arrayOf("A", "B", "C", "D")
    barDataSet.setDrawValues(true)
    barData.addDataSet(barDataSet)
    barData.barWidth = 0.7f

    val linePlanSet = LineDataSet(linePlanEntries, "TOP_A")
    linePlanSet.color = Color.parseColor("#FF0000")
    linePlanSet.setCircleColor(Color.parseColor("#FF0000"))
    linePlanSet.valueTextSize = 5f
    linePlanSet.setDrawValues(true)

    lineData.addDataSet(linePlanSet)

    val lineTotalSet = LineDataSet(lineTotalEntries, "TOP_B")
    lineTotalSet.color = Color.parseColor("#002060")
    lineTotalSet.setCircleColor(Color.parseColor("#002060"))
    lineTotalSet.valueTextSize = 5f
    lineTotalSet.setDrawValues(true)

    lineData.addDataSet(lineTotalSet)

    val lineRateSet = LineDataSet(lineRateEntries, "TOP_C")
    lineRateSet.color = Color.parseColor("#C00000")
    lineRateSet.setCircleColor(Color.parseColor("#C00000"))
    lineRateSet.valueTextSize = 5f
    lineRateSet.setDrawValues(true)
    lineRateSet.axisDependency = YAxis.AxisDependency.RIGHT
    // 값 표시 포맷터 설정
    lineRateSet.valueFormatter = object : ValueFormatter() {
        override fun getFormattedValue(value: Float): String {
            return DecimalFormat("#.##").format(value) + "%"
        }
    }

    lineData.addDataSet(lineRateSet)
